I am currently testing the software and have a question on the map output. I would like to send test maps I have created to my colleagues, however, I need them to be able to view the map at overall city level and them zoom down to street level where the design took place - various locations in the city.

I cannot see an output option that allows such capability. Can someone point me in the right direction, please ?

Scott, you can package the entire project, send over to your coworker and let them open on their machine. Click the GIS Editor button on the top left and click the "package project" item in the drop down list, the current project including the data would then be saved to a zip file.

Or you can save different images on different zoomlevel, and send over the images to your coworker. That's not very convenient though compared with the approach above.
